The International Association of Oil and Gas Producers (OGP) has issued new guidelines for conducting offshore drilling hazard site surveys. The guidelines describe good practice for conducting geophysical and hydrographic site surveys of proposed offshore drilling locations. The document also covers the use of exploration 3D seismic data to enhance or replace acquisition of a site survey.
The guidelines explain the requirements that different types of offshore drilling units have on a site survey. They also emphasize the differing site survey requirements of shelf and deepwater environments.
Objectives of the site surveys and the site survey process are included in the guidelines, as well as suggestions on all phases of a site survey, including initial desk studies and planning, data requirements and geohazard analysis and reporting.
Copies of the guidelines can be downloaded here.
Associated technical notes, to be published separately later this year as OGP Report #373-18-2, will provide supporting technical information and background theory on the various phases of a site survey project and on the vessels and equipment used to acquire site survey data.
